We kicked up the style quotient with two-toned good looks you can wear all day, glossy uppers, bold colors, and a slimmer, more streamlined silhouette. Expect the same OOfoam technology and patented footbed design as our OOriginal to take the stress off tired feet and joints. If you normally wear a whole size: Order the same whole size OOfos.If you normally wear a half size order a half size UP for best fit.
